SM-ASD series No-arc Device

SM-ASD series No-arc Device

Product description


The ASD series DC No-arc devices are the world's first no-arc devices, which solve the arc problems that having been troubling mechanical switches such as relays, push-button switches etc. It can suppress the generation of arcs and is suitable for the arc extinguishing of mechanical switches with various DC circuits. The device can increase the electrical life by over an order of magnitude, improve the current breaking capacity and the withstand voltage level of main circuit, and greatly reduce the amount of maintenance, thus being an extremely "green" product.

Wiring Diagram

1. ASD series products are not suitable for switches arc extinguishing for AC loads.
2. It is recommended to connect a bidirectional transient suppression device between pin 1 and pin 2 of this device in parallel when it is used in case of over-voltage surge.
3. According to customer needs, pin 1 can connect with a fuse in series, and the rated operating current of fuse is 1/3 to 1/2 of the load current.
